This invention relates to an auxiliary top 5 for a gas burner, and is more particularly concerned with anew and useful mproveinent whereby the e tlicienoy of combustion 4 5 and radiation of heat islgreaatly enhanced.

provided with a plurality of openingsthere- 1 in, circumterentially arranged, a gently sloping downturned peripherally arrangedflange,

and a substantially centrally located de-' pressed: portion, whereby the ignited fuel from the burner is directed "upwardly and outwardly by said depressed portion to, insure complete combustion and efficient ra- 2 diation of the heat.

Still another object is to produce an'auxiliary top for a burner having an elevated plateau provided with a;substantially centrally located depressed portion, a plurallty .of orifices eircuinferentially arranged about said depressed portion, a per pherally-located,'

gently sloping {downturned flange, and a plu may of apertures arran 'ed at the uncture of the flange withthe elevated plateau, wherei so by the ignited fnelfrom the burner, is di-' rected. upwardly and outwardly by said depressed portion where it s ooinpletely inixed witlrc'ross currents of a r, provided 3 by the last mentioned apertures,and ispa'ss'ed I upwardly,in its completely ignited condition, through the first mentioned apertures.

When a top according t'oniyinvention is used on ranges employing gas, oil, orv other fuel therein and being deflected toward the sides of the 4 top, whereby the fuel is. thoroughly mixed suitable fuels, with star, round, square, or othershaped burners, it confines the ignited permitting its thorough, ignition,-'and then passes it upwardly either through the openings 18 thereof or as radiant This is accon1- I v I 1,772,407

with air from the openings ,15 and ignited,

' and the resultant flame is passed upwardly through the annular openings 13, a consider- I able quantity of the heat, being also radiated f from thetop itself. v

It is immaterial as to whether the device of g.-, .3'Q u ig- & s employed, easmuch as the heat isfthrown means of the; slopirra walls 11, ina-oirc'le around the center, and 10, is not brought to a pointat the center of said circle. Special e mphasistis laid on thfl fflfli-L ture of the inner depressed portion having sloping walls, inasmuch as it is these walls which properly direct ignited fuel into;

the combustion chamber de'fifiedby the ele- Vate d portion ,9, and theannular flange 14.
